I try to come every Sunday to wander around this hidden conservatory in my favorite Brutalist estate.

Museum exploring connections between medicine, life and art. Fascinating range of exhibitions and great shop, library and cafe. Free entry too. 

Kind of secret, dark, intimate cocktail bar in Soho. Really easy to cozy up on a couch and stay there all night.

The Greenwich Observatory with its green laser beam can transfigure any night sky. If you decide to cross the Thames via the foot tunnel, make sure you look out for the green ray. You can be on one side of the meridian in a minute, and cross to the other side on the next, without even realising it.

I rediscovered this place recently having not been for years and now I keep returning. The geological galleries are my favourites.
